| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| The primary endpoint of the study is to estimate the activity of allopurinol compared with placebo on the change in cell proliferation by assessment of Ki-67 |
|
| E.2.2 | Secondary objectives of the trial |
| Secondary objectives are to investigate the effects of allopurinol on potential biomarkers measured as a change from the baseline Bcl-2, COX-2, topoisomerase-II-a as a measure of apoptosis, IGF-I, IGFBP-3 and IGF-I/IGFBP-3 inflammation indexes u-PCR We will also evaluate the safety and tolerability of the two different scheduled doses of 100mg and 300mg /day of allopurinol. |
